| 摘要 |
<p>The invention relates to a system for applying a powder material, including a housing (1) provided with a bottom (3) and a cover (4), said system further including a dispensing device which is mounted inside the housing (1), said device including an upstream grating (10) and a downstream sieve (11) provided with an upstream (10a) and downstream (11a) lattice of through-openings, respectively, said sieve and said grating being attached to the housing (1) while being stacked axially, with the lattices (10a, 11a) thereof axially staggered, said dispensing device further including a metering plate (12) which is provided with a metering lattice (12a) consisting of through-openings, said plate being translatably mounted in a reversible manner between the sieve (11) and the grating (10), from a metering position, in which the metering lattice (12a) is arranged such that said lattice can be supplied with a metered amount of material through the openings of the upstream lattice (10a), to a dispensing position, in which the metering lattice (12a) is arranged so as to dispense the metered amount of material through the openings of the downstream lattice (11a).</p> |
